Remove the battery door. 2. Slide the [ CHANNEL ] slide switch to choose a channel. 3. Insert 2 x AA size batteries into the battery compartment according to the polarity mark on the battery compartment.. 4. Close the battery door. 5. After inserting batteries, the transmission status LED will light up 1 sec. NOTE: -Ensure to assign different channels of different sensors, in case you need to pair more than one sensors. - Once the channel is assigned to a Wireless Soil Moisture & Temperature sensor, you can only change it by removing the batteries or resetting the unit. - Avoid placing the sensor in direct sunlight, rain or snow. PAIRING THE WIRELESS SENSORS WITH THE CONSOLE The console will automatically search and connect to your wireless sensor(s). Once your sensor(s) pair up successful, the sensor(s) signal strength indication and weather information will appear on your console display. NOTE: During signal transmission, the LED indicator of the sensor will flash. TEMPERATURE DISPLAY On the display of the console which the soil sensor is linked to, temperature reading will be displayed. SOIL MOISTURE DISPLAY Soil moisture can be clarified into 5 different levels: Very Dry, Dry , Moist, Wet and Very Wet. To determine the moisture of soil, the sensor calibrate the moisture into 16 points, and correlate them into percentage value: PointsPercentageLevel 10% Very Dry 27% 313% 420% 527% 633% Dry 740% 847% 953% 1060% Moist1167% 1273% 1380% Wet 1487% 1593% Very Wet 1699% NOTE: The measurement accuracy of the sensor can be affected by the soil condition. For example, the loose soil may get lower moisture level that compare with the dense soil. SENSOR PLACEMENT Select the suitable installation site that insert the sensor probes into the soil around 100mm (4 inch) and sensor should place within 30 meters of the display console to get the best transmission performance. Display console Soil sensor placement 150m Soil (Mounting pole not included) Main body to ground: 1m Depth: 1m NOTE: Signal transmission range of the sensor will be gradually reduced as sensor is inserted deeper into the soil. To achieve best transmission range, install the sensor on the same plain of view as the display console.. RESET THE SENSOR In case of mal-function, press [ RESET ] button to reset the sensor.

INTERTEK TESTING SERVICES RF exposure - 1 of 1 For Maximum Permissible Exposure (MPE) evaluation of the base unit, the maximum power density at 20 cm from this mobile transmitter shall be less than the General Population / Uncontrolled MPE limit in OET Bulletin 65 and meet the requirement listed in KDB447498. For the 915MHz portion of the Sensor of tested model: C3130A, the measured EIRP power was within its production tolerance: -30 dBm (Minimum) and 0 dBm (Maximum).The antenna gain is 0 dBi = 1.00 (num gain) and its maximum source-based time-averaging duty factor is 100%. From these data and its operating configuration – Mobile device, the exposed power density at a distance (R) of 20cm from the center of radiation of the antenna can be calculated according to OET Bulletin 65 as follow: The EIRP Power = -5 dBm = 0.316 mW The EIRP Power source-based time-averaging output power = (0.316 * 1) mW = 0.316 mW The power density at 20cm = 0.316 / 4πR 2 = 0.000063 mW cm -2 In the frequency range of 1,500 - 100,000MHz, the MPE limit is 1.0 mWcm -2 for general population and uncontrolled exposure. As the measured power density at 20cm from the transmitter is lower than the MPE limit, the compliance to the MPE limit can be ensured by indicating the minimum 20cm separation between the transmitter's radiating structures and body of the user or nearby persons. The following RF exposure statement is proposed to be included in the user manual: “ FCC RF Radiation Exposure Statement Caution: To maintain compliance with the FCC’s RF exposure guidelines, place the unit at least 20cm from nearby persons.”
